The first main control module 21 is configured to obtain the location information of the person in distress sent by the positioning module 22, and send the location information to the forwarding device 1 through the first wireless transmission module 23. The first main control module 21 may adopt a microprocessor; for example, a microprocessor of the ST model number STM32 family may be used.
The positioning module 22 is configured to obtain position information (such as current longitude and latitude position information) of a person in distress who falls into water, and send the position information to the first main control module 21; the positioning module 22 can adopt a GPS or Beidou positioning module; for example, a BDS/GPS dual-mode positioning module with the model number UM220-IVN of the Beidou satellite communication company can be adopted, and the positioning module has a satellite positioning function. The beacon machine 2 is worn on the body of the person in danger or fixed on a life jacket, and the position information of the person in danger can be directly or indirectly obtained (through the life jacket).
The first wireless transmission module 23 is configured to send the location information of the person in distress, which is sent by the positioning module 22 and acquired by the first main control module 21, to the forwarding device 1. The first wireless transmission module 23 may adopt a long range wireless communication module (LongRange Radi o, LoRa) or a short range wireless communication module (such as a ZigBee wireless communication module); for example, when the long-distance wireless communication module is used, a low power consumption wireless communication module of macro electric company model H6820 may be used. When a short-range wireless communication module is employed, a low-power, high-performance wireless communication module, model ZM516x, from guangzhou remote electronics may be employed.
The first power supply circuit 24 is used to control whether to supply power to the beacon, i.e. whether to turn on the beacon to make it enter the working state. The first power circuit 24 includes a control switch, a rechargeable battery and a charging circuit, one end of the control switch is connected to the positive electrode of the rechargeable battery, the other end of the control switch is connected to the input ends of the first main control module 21, the positioning module 22 and the first wireless transmission module 23, the output ends of the first main control module 21, the positioning module 22 and the first wireless transmission module 23 are connected to the negative electrode of the rechargeable battery, and the two ends of the rechargeable battery are connected to the charging circuit.
Because the beacon machine 2 needs to be worn on the body of the person in danger or fixed on a life jacket, when the person in danger falls into water after wearing the beacon machine 2 or the person in danger wears the life jacket fixed with the beacon machine 2, in order to prevent the modules and the first power circuit of the beacon machine 2 from being damaged due to water, the modules and the first power circuit of the beacon machine 2 can be sealed in a plastic shell.
The control switch is used for controlling whether the beacon machine is started or not so as to control whether the beacon machine acquires the position information of the person in danger or not. The control switch can adopt a magnetic control switch or a water-sensitive switch. When the magnetic switch is adopted, the magnetic switch can comprise a reed switch and a permanent magnet, and the reed switch is controlled to be in a switch-on or switch-off state by the permanent magnet. Because the beacon machine 2 is always in the closed state when the person in danger does not fall into the water so as to achieve the effect of energy saving, the reed switch is always in the normally open state when the beacon machine is not started, at the moment, the normally closed reed switch can be positioned on the inner wall of the plastic shell of the beacon machine, the permanent magnet is adhered (for example, double faced adhesive tape is adopted) on the position, close to the reed switch 2, of the outer wall of the plastic shell of the beacon machine, and when the beacon machine needs to be started, the permanent magnet only needs to be torn off forcibly.
In addition, the reed switch can be positioned on the inner wall of the plastic shell of the beacon machine, the mounting piece for mounting the permanent magnet is arranged on the outer wall of the plastic shell of the beacon machine close to the reed switch, and the position of the permanent magnet on the mounting piece is adjusted, so that the reed switch is controlled to be in a switch-on or switch-off state. The mounting piece can be a U-shaped guide rail, a flexible sealing strip is buried in a guide rail groove of the U-shaped guide rail to increase the sliding resistance of the permanent magnet, or a spring piece is additionally arranged on the guide rail of the U-shaped guide rail, so that the permanent magnet is convenient to fix. When the permanent magnet slides to the bottom of the U-shaped guide rail, the permanent magnet can be close to the reed pipe, so that the reed pipe is controlled to be in a connected or disconnected state; when the permanent magnet slides to the position far away from the bottom of the U-shaped guide rail or slides out of the top of the U-shaped guide rail, the permanent magnet can be far away from the reed pipe, so that the reed pipe is controlled to be in a connected or disconnected state;
and the water sensitive switch is also used for controlling whether the beacon machine is started or not. The water sensitive switch is positioned on the inner wall of the plastic shell of the beacon machine, and when people in danger fall into the water, the water sensitive switch can be in a conducting state when meeting the water, so that the beacon machine is automatically started when the people in danger fall into the water, the position information of the people in danger can be conveniently acquired, and the position information is sent to the forwarding device 1.
